NEW: Add HTTPRequest::setIP()
API: Rely on HTTPRequestBuilder to set scheme and IP

These changes tidy up HTTPRequest making it a container for information
and removing special logic from it.

This makes it less feature-rich: it doesn’t contain trusted-proxy logic.
This will be able to provided by a middleware.

The new getScheme() method is designed to be closish to PSR-7’s
getUri()->getScheme() equivalent.

There are no more direct $_SERVER references in HTTPRequest.
